UNITED TA WRENCH.

Application filed May 28,

1/ 0 all whom it may concern 7 Be it known that I, CHARLES F. FLETCHER,a citizen of the United States, residin at Farmington, in the county ofMarion, tate of West Virginia, have invented a new ,and useful Wrench;and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to wrenches of the pivoted jaw type and has forits object to provide a device of this character wherein stationary jawcarried by a handle member is provided, said jaw having pivoted theretoa movable jaw carried by a disk which disk is provided with a radiallydisposed shoulder, with which shoulder the vertically disposed adjustingscrew cooperates for moving and holding the pivoted jaw to variouspositions in relation to the stationary jaw.

A further object is to provide the disk of the pivoted jaw with anarcuate recess, in

which recess the coiled spring is disposed, which coiled springcooperates with the pivoted jaw and the body of the handle for normallyforcing the pivoted jaw to open position.

A further object is to provide the adjusting screw with rectangularshaped heads disposed within similarly shaped recesses and held thereinby the spring. Also to provide a thumb engaging nut on the adjustingscrew, which nut cooperates with the shoulder of the disk of the pivotedjaw.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of a wrench, parts beingbroken away to better show the structure.

Fig. 2 is a top plan view of the wrench.

Fig. 3 is a detail view looking into the jaws of the wrench showing thewire cutting recesses.

Referring to the drawings, the numeral 1 designates a handle member, theforward end of'which terminates in a stationary jaw 2. The handle member1 is provided with a Specification. of Letters Patent.

chamber 3, in which chamber is disposed a disk 4 carried by a movablejaw 5 which is pivoted on the screw 6. The disk 4: rotates in thechamber 3, and is rotated by the thumb engaging nut which engages aradially disposed shoulder 8 carried by-the disk 4% and forces the disk4 around against the action of the coiled spring 9, which coiled springhas its end 10 disposed in an arcuate recess in the bottom side of thedisk 4 and its end 12 in engagement with. a rectangular portion 13 of avertically disposed feed screw 1% on which the thumb engaging nut 7 isthreaded. The rectangular shaped portion 13 of the feed screw 14: isdisposed in a rectangular shaped recess: 15 of the handle member and isheld therein by said coiled spring 9. The upper end of the feed screw 14is rectangular shaped and disposed within a rectangular shaped member 16and also held therein by the coiled spring 9. It will be seen that whenthe rectangular shaped portions of the feed screw 14: are disposed inthe recesses 15 and 16 that the spring 9 connecting with the arcuateside 17 of the disk 1 will hold the feed screw and thumb engaging nut 17in place and against displacement. However it will be seen that when itis desired to disassemble the wrench it will only be necessary to removethe single screw 6 and when said screw is removed all of the parts ofthe wrench may be easily removed.

The disk 4 is provided with an inclined recess 18, which recesscooperates with the recess 19 for receiving a wire or the like andcutting said wire when the jaws are forced together, in any mannerdesired. The rear end of the handle 1 is provided with nut receivingrecesses 21 and 22 whereby standard sizes of nuts may be received. It isto be understood that the jaws 2 and 5 may receive therebetween anythingthat is round, such for instance as pipe or rod, however if so desirednuts may be held therebetween.

From the above it will be seen that a pipe and rod wrench is providedwhich is simple in construction and one wherein the parts have beenreduced to a minimum thereby allowing the wrench to be cheaplyconstructed.

The invention having been set forth what is claimed as new and usefulis 1. In a wrench, the combination with a body having a stationarywrench jaw at one end, of a movable jaw provided with a disk, said diskbeing pivotally mounted in a recess of the body, a vertically disposedscrew disposed within the recesses and having its ends providedwithrectangular shaped portions disposed in vertically alined'rectangular shaped recesses, a thumb nut threaded on said verticallydisposed screw, a radially disposed shoulder carried by the disk of themovable jaw with which shoulder the thumb screw engages, a coiled springdisposed with in the recess of the body, said coiled spring having oneof its ends disposed in an arcurecess in the disk, the other end ofsaid'screw engaging the lower rectangular shaped portion of thevertically disposed feed screw, said ieed screw being maintained inengagement with the rectangular shaped recesses by means of the coiledspring and the disk.

2. In a wrench, the combination with a body having a stationary wrenchjaw at one end, of a movable jaw provided with a disk, said disk beingdisposed in a recess of the body, a spring for normally holding saidjaws open, a lug carried by the disk, a feed screw detachably disposedin recesses in communication with the recess of the body, a thumb nutthreaded on said screw and engaging the lug carried by the disk, said iCHARLES FREDERICK FLETCHER.
